Presentation Transcript

  1. Chapter 28: Nuclear Chemistry Nuclear Chemistry… Nuclear Decay Nuclear Stability and Valley of Stability Other Nuclear Reactions Fusion and Fission Detecting Radiation Nuclear Waste and other ….

  2. Nuclear Particles • Alpha particle • Beta particle • Gamma particle a 4 2He β g

  3. Alpha Decay • Alpha particles are a helium nucleus with a +2 charge…

  4. Beta Decay • Beta particles are fast moving electrons with no mass and -1 charge…

  5. Gamma Decay • Gamma radiation is like light and energy from an explosion…it occurs with alpha or beta decay as a secondary product.

  6. Penetration Power

  7. Nuclear ReactionsNuclear Fusion • Nuclear Fusion… Combining of 2 smaller nuclei to make one larger nucleus. • We cannot conduct nuclear fusion to produce energy because it requires too much energy input and too much hear.

  8. Nuclear Fission • Nuclear Fission is the reaction used to power submarines, aircraft carriers, and nuclear power plants. • Fission is the splitting of atoms into 2 smaller nuclei.

  9. Detecting Radiation • Gieger counters count electron strikes in a gas tube. • Scintilation counters count electron strikes to a phosphorescent screen. • Film ID badges are worn by employees and analyzed at night or at the end of the week to see radiation strikes.
